' Application filed March-5, rssr. (N0 model.)

To all whom it may concern.-

Be it known that 1, JOHN GEARY, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvementsin Electric Gas-Lighters; and I do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanyingdrawings, which form a part of this specification, in which- Figure 1 is a side view, and Fig. 2 a top View, of an electric gas-lighter embodying my improvements.

My invention has relation to electric gaslighters of that class wherein one of the electrodes is carried upon a lever pivoted to the valve of a gas-burner, said electrode comprising a spiral spring, one of whose ends extends out from the lever and contacts with the other electrode, which is rigidly fastened to an insulated collar on the burner.

It has been found that in electric gas-lighters of the class above mentioned the movable electrode after being in use for a short time frequently catches and refuses to pass over the stationary one, thereby leaving the circuit of the battery'in closed circuit and causing it to run down.

My invention consists in the combination, with a gas-burner having a vibrating arm carrying an electrode comprising a spiral spring with a lateral extension at one end, of an electrode attached to a pivoted and weighted lever pivoted to an insulated collar on the gas burner, and provided with a stop to limit its movement in one direction, whereby when the lever is caused to swing past the electrode on the burner the electrode on the lever will come into contact with the oneon the burner and will, by reason of the spiral spring forming a portion thereof, slip past, and on the return of the lever the electrode on the burner will yield and permit the electrode on the lever to pass freely by.

My invention further consists in the combination, .with an electrode pivoted to the burner, of an electrode secured upon a spring-arm, which is pivoted to the lower portion of the burner, below the cock, and operated by a dog upon an arm secured to said cock to come into contact and slip past the swinging .electrode, thereby producing the necessary spark. My invention still further consists in peculiar construction and combination of parts,

whereby the gas may be lighted andturned down to any desired point without danger of leaving the electrodes in contact, and thereby running down the operating-battery.

Referring to the accompanying drawings, A- represents the gas -burner; 13, the pipe which supplies gas to said burner; and G is the cock by which the flow of gas is regulated.

D represents a split collar, secured in position upon the tip a of burner A by a screw, (1. Upon one side of collar D is a lever, E, pivoted on a screw, d, said lever having a weighted end, 6, and opposite the weight an electrode, F, whose upper end is bent over to one side, as shown. A stop, f, is formed upon the collar D, and serves to, limit the movement of the weighted lever in one direction, a stop, f, serving to limit its movement in the opposite direction.

G is a lever pivoted at g to the gas-pipe B, and curving around the cock 0 and projecting up level with the tip of the burner. Upon the upper end of the lever G is secured a spring-electrode, H, having a projecting arm, h, which contacts with the electrode F when the lever swings past the same. A plate, I,

is attached to the side of the burner next to lever G, and near the edge of said plate is a longitudinal slot, c, through which thelever G projects, and in which it works, said slot serving to limit the movement of said lever in either direction, and preventing any lateral displacement of the same.

K is a spring secured at one end to the gaspipe in any desired position, its free end pressing against a pin, is, on the inside of lever G.

L represents an upright arm upon the cock 0, outside of lever G, and M a weighted dog, pivoted upon the inside of said arm by a screw, m, stops a n serving to limit the movement of said dog and preventing its accidental displacement. A tooth, g, is formed upon the edge of lever G, and-projects out toward the dog M, and engages therewith during a portion of the movement of lever G.

The operation of the invention is as follows: In Fig. 1 of the drawings the cock is in position to entirely shut off the flow of gas. When the gas is turned on, the dog m engages with IOO the tooth g and forces the lever G along the slot in plate I, causing the electrode H to come against and slip past electrode F, the latter being prevented from moving by its stop f. WVhen the lever has gone such distance that the electrodes are no longer in contact, the dog m loses its grip upon tooth g by reason of the fact that the pivotal position of the lever and the arm on the cock are placed one above the other, and the lever is forced back to its original position by a spring, K. The gas, being now lighted, may be turned down to a mere spark, if desired, and left in that condition, it being understood that the dog will engage with the tooth upon the lever only when the gas is turned completely out. As the electrode H is returned to its original position it of course comes into contact with the pivoted electrode 1?; but the latter yields easily, as there is no danger of their remaining in contact and thereby running down the battery.

WVhatI claim as my invention is as follows:

1. The combination, with a swinging arm carrying a yielding electrode, of a lever pivoted on the gaspipe, provided with an electrode, and adapted to engage with an arm on the cock, substantially as described.

2. The combination of swinging lever E,

having electrode F, weight (2, and stop f, with lever arm G, having the yielding electrode H, 0 and arm L, having dog M, all constructed and arranged substantially as described.

3. In a gas-lighting apparatus, the combination, with an electrode on the burner and an electrode on a lever pivoted on the gas 35 pipe, of a lever attached to the cock, and provided with a pivoted dog which will engage with said lever and move it past the electrode 011 the burner, and means, substantially as described, whereby said lever will be loosed 40 from engagement with the dog when the gas is turned on, substantially as described.

4. In an electric gas-lighter, the combination, with a pivoted lever carrying a yielding electrode, of a swinging and weighted lever 5 attached to and pivoted upon an insulated collar upon a gasbnrner carrying an electrode. and provided with a stop to limit its movement, substantially as set forth.

In testimony that I claim the foregoing I 50 have hereunto set my hand.
